Have you read Nassim Taleb? An antifragile system must be composed of fragile components... and smaller systems are nested as components in larger systems. Interesting enough, most fans of Nietzsche I know are religious -- religious existentialists -- like Kierkegaard, Dostoyevsky, Shestov, and Gabriel Marcel.

Nietzsche believed in eternal reoccurrence, the idea that with infinite time and a finite number of events, events will recur again and again infinitely. His beliefs aligned well with the concept of samsara and cyclical history of the universe in Hinduism and Buddhism. The Christian existentialists interpreted this as faith: the highest passion to make the same choice over and over again, even if you have to live infinite life times. This faith is identical to amor fati. One who eliminates living in "bad faith" as defined by Sartre, can be considered a Buddha. Sartre also considered himself to be an atheist, yet the same themes are found in Dante's Divine Comedy.

When Nietzsche said that "God is dead", he didn't think that was a good thing. He simply interpreted as part of the cycle of history that all value systems must die eventually, and that a new value system will arise after its inevitable fall. Spengler's Decline of the West described such lifespans of civilization spheres following Nietzsche's thoughts. Nihilism is in the context of cultural sentiments of the era it occurs in. The lack of value, as with any other value, is impermanent.

Nietzsche's ideas, as with most existentialists, are basically identical with Vajrayana Buddhism. He's nothing like the modern "New Atheists." At this point, even the word "religion" is incredibly ambiguous and lack much practical utility. It's only useful for these who believes in a literal sky daddy, and these who get their panties in a bunch to actively oppose the imaginary sky daddy because they are rich and bored. Everyone else is in the middle and are fluid depending on the circumstances.
